BOX STRAP SEAL.

Application med september e, 1923. serial No. 661,325.

To aZZ whom, 'it may concem: Be it known that I, FRANCIS L. MCGARY, a citizen of the United States, and a resident of Hardinsburg, in the county of Breckenridge and State of Kentucky, have invented certain new and useful Improvements in Box Strap Seals, of which the following is a specification.

This invention relates to box strap seals or seals for the ends of barrel hoops and has ,for its object the provision of a device which may be readily applied to the overlapped ends of metal straps and which is provided with slots adapted to neatly receive portions of the deformed ed es of the overlapped straps for locking t e loverlapped ends of the straps together.

A. further object of the invention is the provision of a device adapted to receive the overlapped ends of metal straps with por-v tions of the overlapped ends being deformed simultaneously with the edges of the device whereby straps are interlocked together and interlocked with the device.

This invention will be best understood from a consideration of the following de tailed description in view of the accompan ing drawing forming a part of the speci cation; nevertheless it is to be understood that the invention is not confined to the disclosure, being susceptible of such lchanges and modifications which shall dene no material departure from,l the salient features of-.the invention as expressed in the apnded claims.

In the drawings:

Figure 1 is a view in perspective of the pair of overlapped strais locked together by my improved metho Figure 2 is a. view in perspective of the metal sealing device constructed according to my invention.

Figure 3 is a transverse section taken along the line 3-3 of Figure 1.

Figure 4 is a view in perspective of a modified form of the locking device.

Fi ure is a'transverse section taken' along the line 5-5 of Figure- 4.

Figure 6 is a view in perspective of the form of metal sleeve shown in Figure 4.

Referring more particularly to the drawings 1 and 2 designate metal straps having their ends in overlapped relation and received between the base plate 3 and the inturned spaced flanges 4 of a metal sleeve 5. While I have shown the free edges of the inturned flanges 4 spaced apart they may be in engagement with each other without affecting thel scope of the invention.

The inner side edges 6 of the flanges 4 are spaced from each other while portions of the base 3 defined by the inner edges 6 are cut away as shown at 7 to form slots and adapted to receive the deformed peripheral edges 8 of the overlapping straps 1 and 2 when some suitable instrument has been applied to the edges exposed to the slots 7. The tongues 8 of the straps 1 and 2 are bent suliCient-ly upward to engage the edges 6 of the flanges 4 and the side edges 9 of the slots 7 and thereby not only lock the sleeve 5 to the metal straps but rigidly lock the ends of the straps together and prevent separation of the same.

The metal sleeve 5 is formed from a rectangular blank by cutting out portions to vform the slots 7 and the spaced side edges 6 of the flanges 4 when the flanges 4 are bent in spaced'relation beneath the base 3 of the sleeve 5.

By cutting away the member 5 to form the slots 7 and the spaced flanges 4 the base member 3 of the sleeve is bent at that portion between the slot 7 and conforms to the shape of an article to which straps 1 and 2 have been applied and secured.

Referring to Figures 4 to 6 inclusive, it will be seen that a similar result is obtained by forming a sleeve 5 but omitting the slots 7 and the spaced side edges 6 of the flanges 4. The flanges 4* of the sleeve 5'l extend the full length of the sleeve but due to the lack of the slots 7 the base 3'L will not readily conform to the shape of the container to which the straps are applied and this form of sleeve, is better adapted Yfor containers which have flat sides.

The same form of` tool which has been applied in shearing the side edges of the straps 1 and 2 to form the tongues 8 is likewise applied to the overlapping straps 1 and 2a and likewise to the embracing sleeve 3". The peripheral edges of the sleeve 5 and the straps 1 and 2 are sheared an bent upwardly as shown in Figures 4 and 5 thereby causing the edges of the tongues 9 embracing the raised portion 10 of the sleeve 5a to secure the sleeve 5 in locked relation with the ends of the straps 1 and 2 1 thereby locking the ends of the straps together.

The shearing of the lateral edges of the straps is performed in an upward manner and the lips-on the straps thus formed between the sheared portions are bodily raised either through the slots in the sleeves, shown in Figures l to 3, or the lips and the adjacent metal of 'the sleeves shown in Fig'- ures` 4to 6 inclusive are bodily raised simultaneoisly. Y

What I claim is: A

1. A strap seal comprising overlapped strap ends and a sleeve embracing said ends, said sleeve being provided with transverse slots extending inwardly of the opposite` longitudinal edges of the sleeve, portions o the longitudinal edges of the strap ends where embraced by the sleeve being sheared from below and transversely of the sleeve to form lips, said lips being elevated above the plane of the sleeve and having their side edges in engagement with the side edges of the slot whereby the strap ends of the sleei are locked rigidly together.

2. A strap seal comprising overlapp'e strap ends and a sleeve embracing said end said sleeve being sheared at its longitudin: edges to provide transverse slots extendir inwardly of the opposite longitudinal edg= of the sleeve, the metal of the Sleeve whe; sheared upon the slot being forced upward and projecting above the plane of the sleev portions of the longitudinal edges of tl strap ends where embraced by the slee` f being sheared from below and transverse of the sleeve to form lips, said lips havir their side edges in engagement with the si( edges of the slots inthe sleeves, the li*E being embraced by'the upturned shear( portions of the sleeve. 4
